Abstract: 1,152,221. Assembling upholstery springs. SPUEHL A.G. 7 Feb., 1967 [12 July, 1966], No. 5767/67. Heading A4M. [Also in Division H2] A machine for interconnecting the end convolutions of adjacent rows of springs 1 by a helical wire 4 includes a safety device which automatically switches off the motor M driving a device 2 for coiling and advancing the wire 4 if the latter is obstructed or by-passes any one of a row of pairs of tongs Z 1 -Z n  locating the convolutions to be connected. The machine is started by a push button D, the motor M being started automatically by a switch S, when the springs 1 are positioned in the tongs and stopped by a switch S 2  actuated by a senser 6 engageable by the wire 4 adjacent the final tongs Zn. The switches S 1 , S 2  act througha cut-out W including a three-pole switch 9, a coil 8 andthree contacts W 1 , W 2  and W 3 . A monitor 15 senses the speed of the advance of the wire 3 entering the coiler 2 and includes a contact K in parallel with the contact W 3 . In the event of a wire 4 being obstructed the monitor 15 senses the resulting reduced speed of the wire 3 to move the contact K to open the switch 9 and after a short delay stop the motor M. The control circuit includes a main relay H and two delayed-release relays R 1 , R 2  which in a faultless operating cycle: remain energized until the switch S 2  stops the motor M. The first relay R 1  has a short release lag of 0.5 secs. so that the holding circuit is rapidly broken if a wire 4 meets an obstruction. The second relay R 2  has a release lag of 5 secs. which slightly exceeds the time to advance a wire 4 over the whole length of as row of springs 1 and is operative to break the motor circuit if the wire 4 has deviated from the line of tongs Z 1 -Z n . A switch 19 is manually operable to reverse the motor M following a fault.
